Linear Inequality Solver
Solve a supported linear inequality, see its solution and review the steps. When dividing by a negative number, remember that the inequality sign must reverse.
Solve a linear inequality, visualize its solution, and understand the working with step-by-step explanations.

Graph
y > 2x + 1Example: solving a one-variable inequality
Start: 2x + 3 ≤ 11
Subtract 3: 2x ≤ 8
Divide by 2: x ≤ 4
The solution contains every real number less than or equal to 4.
Enter the example into the calculator above to calculate the solution. Only supported linear expressions are accepted.
Supported inputs and common mistakes
The solver accepts linear expressions in x and
y, constants, and one inequality sign. Reverse the sign
when multiplying or dividing by a negative number. Parentheses,
fractions written with /, compound inequalities,
absolute-value expressions, and systems are not supported.
